The INFN project MAPS_3D

MAPS_3D is a project of Istituto Nazionale di Fisica Nucleare which aims to implement an unprecedented characterisation of magnetised laboratory plasmas by means of high-resolution spectropolarimetry in the visible range. This observational technique is routinely applied to astrophysical plasmas in order to derive physical parameters of stars. Through the experimental set-up of MAPS_3D spatial resolution of the emitting plasma will be obtained, giving the possibility to localise the emitters from hot and cold plasma regions, as well as to estimate the charge state distribution. This innovative plasma characterisation, not achievable by means of the present diagnostic techniques, will allow a better comprehension of laboratory plasma structure, heating processes and magnetic confinement, with strong implications for Accelerator Physics, Plasma Physics, Astrophysics and Nuclear Astrophysics.
